2. Description of the Related Art Permanent wave treatment of hair with a permanent wave composition is performed by applying a first agent for permanent wave containing a reducing agent such as thioglycolic acid or a salt thereof, cysteine or a salt thereof to hair. The hair is wound around a rod or the like (the hair may be wound around the rod and then the first agent may be applied to the hair). In this state, the disulfide bond of cystine in keratin, which is a protein (protein) of hair, is reduced by the reducing agent. With a second agent for permanent wave mainly containing an oxidizing agent such as sodium bromate and hydrogen peroxide.
This is done by reforming the disulfide bond at a new location and immobilizing the wave.
